For a long time there have been a number of possible "holy grails" for digital preservation, ideas that if it were possible to implement them would transform the problem. One of them has been the idea of an Internet-scale peer-to-peer network that would use excess disk storage at everyone's computers, in the same way that networks like Folding@Home use excess CPU, to deliver a robust, attack-resistant, decentralized storage infrastructure. Intermemory, from NEC's Princeton lab in 1998, was one of the first, but the concept is so attractive that there have been many others, such as Berkeley's Oceanstore. None have succeeded in attracting the mass participation of projects such as Folding@Home. None have become a widely-used infrastructure for digital preservation because without mass participation none provides the needed robustness or capacity.

Yesterday was the 30th anniversary of Bob Scheifler's announcement of the first release of the X Window System. Congratulations to Bob and the other pioneers! That doesn't include me - I started work at Sun on X a couple of years later by doing the first port (of Version 10) to non-DEC hardware.

I've already written skeptically about the concept of quasi-immortal media as a solution to the problem of digital preservation. But the misplaced enthusiasm continues. The latest wave surrounds Facebook's prototype Petabyte Blu-Ray jukebox; one of its touted features was the the media had a 50-year life. The prototype is extraordinarily interesting, and I hope to write more about it soon. But I doubt Facebook or anyone expects that the hardware will still be in use in 10 years, let alone 50. After all, you can search any large-scale data center in vain for 10-year-old hardware. So why is a 50-year media life interesting in this application? Follow me below the fold for yet another dose of skepticism.

More than four years ago Marc Andreesen gave a talk at Stanford's Business School in which, among many other interesting topics, he talked about the problems the New York Times had dealing with digital media. The recently leakedNYT Innovation Report 2014, the result of a six-month review headed by the Times' heir apparent, shows how prescient Andreesen was. Below the fold, some evidence.

The Hargreaves process in the UK has resulted in copyright reform legislation which has passed Parliament and is due to receive Royal Assent this month. Among the numerous improvements it contains are that data mining is included in the right to access, that libraries can make fair dealing copies for their readers, and that sound and video are treated the same as text in most cases. Of particular importance is that in most cases contracts will not be able to override these permissions.
